TestKing Ltd. receives product information from manufactures in the form of an XML documents. The product information is stored in a Microsoft SQL Server database. The format of each XML document varies. Each one is located in a MemoryStream object named newProds. You create a merge procedure that reads data and schema information in a DataSet object and merges the information into your database. You now need to write code to transfer the XML document and its schema into a DataSet object. Which code segment should you use?
A. DataSet products = new DataSet(“prodInfo”);
XmlTextReader reader = new XmlTextReader(newProds);
XmlValidatingReader validReader = new
XmlValidatingReader(reader);
while (validReader.Read()) {
products.WriteXml(validReader.Value);
}
B. DataSet products = new DataSet(“prodInfo”);
products.ReadXml(newProds);
C. DataSet products = new DataSet(“prodInfo”);
XmlDataDocument document =
new XmlDataDocument(products);
document.DataSet.ReadXmlSchema(newProds);
D. DataSet products = new DataSet(“prodInfo”);
string myXmlData =
Encoding.UTF8.GetString(newProds.ToArrary());
SqlDataAdapter adapter =
new SqlDataAdapter(“LoadSchemaType=XML”,myXmlData);

You are developing an application to monitor store inventory. When inventory falls below a specified level, the application automatically generates a purchase request. Suppliers have requested that you transmit purchase requests to them in an XML document. Suppliers will accept the XML document in any valid form, except they do not want the data set definition to be included in the XML file. You create a method named GeneratePurchaseRequest. You write the code to populate a DataSet object named myDataSet with the purchase request data. You define a variable named fileName that contains the name and path of the output file. You need to create an XML file from the data in myDataSet by adding code to GeneratePurchaseRequest. You want to accomplish this task by writing the minimum amount of code. Which code segment should you use?
A. myDataSet.WriteXML(fileName, XmlWriteMode.IgnoreSchema);
B. myDataSet.WriteXML(fileName, XmlWriteMode.WriteSchema);
C. myDataSet.WriteXMLSchema(filename);
D. TextWriter myWriter = new StreamWriter(fileName);
myDataSet.WriteXMLSchema(myWriter);
ANSWER : A

ANSWER : A, C
You develop an ADO.NET application that uses a Microsoft SQL Server database and a SqlClient data provider. Your application includes the following four code segments, which are each called once:
SqlConnection myConnection1 = new SqlConnection();
myConnection1.ConnectionString = “Data Source=TestKServer;”
+ “Initial Catalog=Billing;Integrated Security=true”;
myConnection1.Open();
SqlConnection myConnection2 = new SqlConnection();
myConnection2.ConnectionString = “Data Source=TestKServer;”
+ “Initial Catalog=Billing;Integrated Security=True”;
myConnection2.Open();
SqlConnection myConnection3 = new SqlConnection();
myConnection3.ConnectionString=
“Data Source=TestKingServerB;”
+ “Initial Catalog=Search;Integrated Security=true”;
myConnection3.Open();
SqlConnection myConnection4 = new SqlConnection();
myConnection4.ConnectionString = “Data Source=TestKServer;”
+ “Initial Catalog=OrderEntry;Integrated Security=true”;
myConnection4.Open();

B. Two
C. Three
D. Four
